17.2 Rates, Forms, Solvency, and Guaranty Associations

Rate Regulation Goals

Every state's rating law shares three goals: rates must be adequate (high enough to keep the insurer solvent), not excessive (not unreasonably high for the coverage), and not unfairly discriminatory (insureds with the same loss exposure pay the same rate). Memorize this triad — it appears on nearly every national exam. Unfair discrimination means charging different rates to insureds of the same class and hazard; charging different rates based on actual differences in risk is legal and expected.

Rate Filing Systems

States use several systems to control how rates take effect:

Rating Terminology

Know these terms cold: the rate is the price per unit of exposure; the exposure unit is the basis of measurement (e.g., $100 of value, per car, per $1,000 of payroll); and the premium = rate x number of exposure units. Pure premium covers expected losses; the loading adds expenses, contingencies, and profit; together they form the gross rate. Manual (class) rating prices large homogeneous groups, while merit/experience rating adjusts a specific insured's premium up or down based on actual loss history.

Advisory Organizations and Loss Costs

Insurers commonly buy data and standardized forms from advisory (rating) organizations such as ISO (Insurance Services Office). ISO develops loss costs — the pure-premium portion of the rate reflecting expected losses and loss-adjustment expense, but excluding the insurer's own expenses and profit.

ISO also publishes the standardized forms tested on the exam, including the HO-3 (HO 00 03) homeowners special form, the CGL (CG 00 01) occurrence form, the PAP personal auto policy, and the commercial Building and Personal Property Coverage Form (CP 00 10) paired with Causes of Loss forms (CP 10 10 basic / 20 broad / 30 special). Each insurer multiplies the published loss cost by its own loss cost multiplier (covering expenses and profit) to arrive at the final filed rate.

Worked Example — Coinsurance

Most commercial property and many homeowners forms contain an 80% coinsurance requirement. The penalty formula is:

(Did Carry / Should Carry) x Loss − Deductible = Payment

A building valued at $500,000 must be insured to at least 80% = $400,000. The owner carries only $300,000 and has a $10,000 partial loss with a $1,000 deductible:

• Should carry = 0.80 x 500,000 = $400,000
• Ratio = 300,000 / 400,000 = 0.75
• 0.75 x 10,000 = 7,500 − 1,000 deductible = $6,500 paid

The insured absorbs the rest as a coinsurance penalty for underinsuring. Note that coinsurance only penalizes partial losses; had the insured carried at least the required amount, the loss would be paid in full up to the limit. The deductible is always subtracted after applying the coinsurance ratio.

Worked Example — ACV vs. Replacement Cost

Actual Cash Value (ACV) = Replacement Cost − Depreciation. A roof costs $12,000 to replace and is 60% through a useful life (60% depreciated):

• Depreciation = 0.60 x 12,000 = $7,200
• ACV = 12,000 − 7,200 = $4,800

Under an ACV settlement the insurer pays $4,800 (less any deductible). Under a Replacement Cost (RC) settlement the insurer pays the full $12,000, typically on a two-step basis: ACV first, then the depreciation holdback once repairs are actually completed.

Solvency Oversight

Keeping insurers able to pay claims is the heart of regulation. Core tools include:

• Financial examinations, typically every 3–5 years.
• Annual statements filed on the NAIC blank using statutory accounting (SAP), which is more conservative than GAAP.
• Risk-Based Capital (RBC) — a formula setting minimum capital relative to risk; falling below thresholds triggers escalating action up to mandatory control / seizure.
• Reserves — loss reserves and unearned premium reserves.
• Reinsurance to spread large or catastrophic exposure.

Guaranty Associations

Every state has a guaranty association that pays the covered claims of insolvent admitted (licensed) insurers. It is funded by assessments on solvent member insurers doing business in that state — not by taxpayers and not pre-funded in advance. Coverage is subject to per-claim and aggregate caps set by state law.

Two guaranty-association traps appear constantly on the exam:

1. Guaranty funds protect policyholders of admitted insurers only; surplus lines / non-admitted insurers are not covered, which is why agents must give insureds a surplus-lines disclosure.
2. Producers may not advertise or use the existence of the guaranty association as an inducement to buy insurance — doing so is an unfair trade practice subject to fines and license action.

Other Valuation Methods

Beyond ACV and replacement cost, the exam contrasts these valuation bases:

• Functional replacement cost — repair with reasonable modern materials of like function (e.g., plaster replaced with drywall).
• Agreed value / stated value — a value set in advance for hard-to-value property such as fine art; suspends the coinsurance clause.
• Market value — sale price including land; generally not used for building physical-damage settlement.
• Valued policy laws — in some states a total loss to a structure pays the full face amount regardless of ACV.
